To tf/Z whom, it may concern:

Be it known that 1, WILLIAM ENRIGHT, a citizen of the United States,residing at Detroit, county of Vayne, State of Michigan, have invented acertain new and useful lmprovement in Flanging-lVlachines; and l declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to Hanging-machines, and has for its object animproved machine adapted to bend and stretch the metal and produceflanges on a large tube of metal.

In the construction of large tanks and standpipes and similar vesselsthat are intended to contain large quantities of liquids the structureis made in sections bolted together. It is desirable to prepare themetal sections of the tank with flanges that are bent outward or inwardat the ends of each lcylindrical section and arranged so that contiguoussections may be secured together with rivets or bolts that pass throughcontiguous flanges; and the object of thisl invention is to produce anadlinstable machine capable of turning such flanges on cylinders orbarrels of' different lengths and of different radii.

In its general features the machine comprises two rolls that act as arolling vise or rolling holder for the metal that has been previouslybent to tubular form. Provision is made to add to the rolls, so that atubular body of any desired length within the capacity of the machinemay be flanged. and the entire framework which supports the rolls mustnecessarily be adjusted to correspond with the length of' the selectedroller. Provision is made also to support a sheet of metal bent intubular form and to use tubes or barrels of different diameter withquite a large range of capacity, and provision is made to adinstandregulate the several working parts of the machine to perform theirduties properly with any one of the selected sizes, either as to lengthor diameter.

In the drawings, Figure 1 is a plan view of part of the machine. 1n theview shown here the machine is shown as expanded to its full capacityand contains three auxiliary pair of vise-rolls in addition to the mainpair of viserolls. Fig. 2 is a section of a tubular body with theflanges turned thereon. Fig. 3 is a plan view of the machine, showing'details of the main driving mechanism. (The beam companion to 21 isvomitted.) Fig. A is a plan view of a part of the inner frame. (The meansfor holding the two vise-rolls yieldingly together is here shown.) Fig.5 is a longitudinal vertical section showing the stead y-arms by whichthe tubular body is held. Fig. 6 shows the parts connected with thearbor on which the Hanging-roll revolves. Figs. 7, 8, and 9 are detailsof parts. of the steady-arm shown in Fig. 12. Figs. 10. and lli' aredetails of the holding device shown in Fig. A. Figs. 12 and 13 arelongitudinal sectional views showing in detail a stead y-arm, several ofwhich are seen in end elevation in Fig. Figs. 14, 15, 16, 17, and 19show details of several of the parts shown in Fig. 6, Fig. 18 is ahorizontal section of the device by which the Hanging-roll is swung.

In the machine which embodies this invention there is an externalframework. rI here are two rolls which are utilized to hold the shell orbarrel of tubular metal that is under treatment. The two rolls will behereinafter called the vise or the rolling vise.7 The `effective lengthof this vise may be varied by adding auxiliary rolls on the rollshafts.One of the roll-shafts is journaled at one end in the main frame, andthe other end is journaled in a bearing that is slidingly supported in abracket. The bracket is built out from thc main frame. rlhe otherroll-shaft is supported at both ends in an auxiliary frame that has asliding movement longitudinal of the main frame.

The main frame is made with two heavy built-up side frames, one ofwhich, located at the rear of the machine, (the side which is shown atthe top in Fig. 3 and shown in ele vation in Fig. 5,) is built oflongitudinal stringers Q1, corner-posts 18 and 19, with suitableintermediate posts I7, and brace 16, bottomstringer 2, and horizontalintermediate stringere 2, The other side frame, at the front of themachine, is shorter, and the heavy top Stringer 21 is omitted from thisfront beam. The front beam carries one end of the shaft 14 and supportsthe ways for some of the adjustable parts which will be described, butdoes not support the heavier parts of the mechanism. The two side beamsare secured together by suitable cross-bars A. The side beams supporthorizontal brackets 3", on which rest side beams 7l of an inner movableframe. The side beams 7l are connected by cross-beams 22 and 23 andcross-beams B and IOO IIO

C, all of which are provided with numerous bolt-holes and which holdsecurely the remaining parts which comprise the inner' frame, one partof which on the side R remains fixed in position with respect to sidebar 71. The other part on the side L is shifted to bring this side ofthe inner frame to its proper place with reference to the number ofauxiliary rolls that are in use.

Outside the main framework is the driving mechanism which communicatesmotion from any suitable source of power from drivingwheel 135, throughclutch 35 on driving-shaft 34 and chain of gearing' from pinion 36, togear 37 on the shaft 13 of roll 3. A gear 131 on the shaft 13 mesheswith 'gear 141 on the shaft 14 of roll 4, and the power thuscommunicated to the machine drives the rolls 3 and 4in oppositedirections. The other actuating mechanism of the machine may bemanipulated or may be power-driven. It is shown in the drawings ashand-driven. One end of the shaft 13 is held in bearings in the rightside beam, and to this right side beam is secured a bracket 11, whichsupports a sliding bearing 12, held in its selected position to the'bracket by bolts. One end of the shaft 14 is held in bearings in theright side of the inner frame, and the other end is journaled in thesliding part of the inner" frame at the left end of the roll.

The cross-beams 22 and 23 and C and Bare provided with bolt-holes 24,through which pass the bolts which secure the inner frame together, andthe length of each part of the rolling vise may be added to ordiminished by using or laying' aside one or more of the auxiliary rolls,of which rolls 31, 32, and 33 are used on shaft 13 with roll 3, androlls 41, 42, and 43 are used on shaft 14 ofroll 4.

The shaft 13, with the rolls mounted on it, is held in stable position.The shaft 14, with the rolls mounted upon it, is slightly movable withrespect to the shaft 13 and is actuated by means of screws 51 and 52.(See Figs. 4, 10, and 11.) The stems of the screws 51 and 52 passthrough bearings 3 in the cross-bar A, which is a cross-bar of the mainframe, and the stemsare journaled in this cross-bar, and each isslightly movable along its own axis, but is normally held projectedinward, bearing against the sliding inner frame by the tension ofsprings 54, each of which encircles the stem of its proper screw andeach of which bears against the cross-bar A and the collar 53 on itsproper screw. Each of the screws is provided with a sprocket-wheel 152,and the two sprocket-wheels are coupled by a chain 55, so that both thescrews are actuated simultaneously by means of the handwheel 56.

The tubular body of metal on which the i'iange is turning' is placedbetween the rolls 3 and 4 of the rolling vise and rests on steadyarmsthat are held to the right frame-beam.

The inner surface of the tube engages against supporting-rolls 50, 60,70, 30, and 90, which, with the brackets that support them, areadjustable to accommodate diierent sizes of tubes. The flanges areturned by rolls 61 and 62, which are similar in construction andsimilarly actuated. Both the Hanging-rolls are swung to allow thetubular body which is to be treated to be inserted between the rolls 3and 4, and both have a horizontal movement radial with respect to theroll 4, which movement takes placeduring the progress of turning theflange. The rolls are actuated along this radial path as the anges areformed. The two movements will be best understood by examining' Figs. 6,14, 15, 16, conlining the description to the mechanism connected withthe iiange-turning roll 62, which is similar in all respects to themechanism connected with the flange-turning roll 61. The roll 62 iscarried on a hollow hub 36, that projects from a yoke 72. This hollowhub 36 and the yoke slide on an arbor 64, that is pivotally connected bypivot 65 to the auxiliary frame, whose side beams 71 slide on track 67,supported on bracket 3a. The unpivoted end of the arbor64 engagesthrough yoke 72 on the frame, and the slide-rods 63 and 69 arethemselves each made in two parts united by pivots 75, which permit theend of the frame and the arbor 64 to swing when the pivots 65 and 75 arein axial alinement. The end of the arbor 64 is supported in a bearing76. (See Fig. 16.) The bearing is swiveled in afork 77, the stem ofwhich is provided with a screw 77a and extends through a journaled nut73 on the auxiliary frame. On the outer end of the nut there is asprocket-wheel 79, connected by a sprocket-chain to wheels 31, and thewheels 31 are on cross-shafts 5, connecting the two similar frames whichcarry the two rolls 61 and 62. The slide-bars 63 and 69 are connected bycross-head H, through which runs a screw 32, swiveled to the frame ofvise-roll 4 by connections shown at 33. On the screw 32 isasprocket-wheel 34, by which the actuating-screw is connected with andmade to act contemporaneously with the corresponding screw in connectionwith roll 61. An actuating hand-w heel 95, through sprocketwheels 31.engag'es the chains to actuatc the sprocket-wheels 79 and nuts 73simultaneously. rThe hub 36, with the tlanging-roll journaled thereon,slides on the arbor 64, and the frame-bars engage through guides 37and33, so that the frame, hub, yoke, and roll move together, while thescrew 32 remains practically fixed in position, although revoluble. Atthe junction between the fork 77 and bearing 76 there is provision madefor play of theparts by eng'aging the trunnion-screws of bearing 76through oval slots 177 in the branches of the fork 77. The looseengagement allows the screw 77l to maintain its position with respect tothe frame and allows IOO the arbor 64 to swing as the screw 7 7 a isadvanced along its own axis.

The tubular body under treatment is held on the rolls 50, 60, 70, 80,and 90, and these are adjustableto correspond with the size of the tubeunder treatment. The means of this adjustment will be understood from anexamination of Figs. 5, 12, 13, 7, 8, and 9. There are Vseveraldiverging rail-guides, one for each steady-roll. Each rail-guide has aflanged track 101, on which engages a grip 102. To the grip is secured aplate 108, in which there is a circular groove 104. The grip-plate isheld in its adjusted position on the track by set-screws 105 and 106.The circular groove 104 is undercut, and a circular plate 107 rests onthe front of the plate 103 and is held by bolts 108, whose heads engageunder the flanges which overhang' the groove 104, and by means of theboltsthe plate is held in any position of rotary adjustment. The plate107 supports a bracket 111 and above the bracket has a bearingleccentric to its center, in which is journaled one end of the shaft 110of roll 109. The outer end of the shaft 110 is journaled in the end ofthe bracketarm 111. With this construction the bracket can be adjustedaround the shaft so as to bring a surfaceof the steady-1011109 tocontact the inner surface of the tubular body under treatment and so asto swing' the bracket to a position that the arm part of it will notcontact the surface of the tubular body.

The operation of the machine is as follows: The machine is set to thedesired width. The rolls 50, 60, 70, 80, and 90 are adjusted to theproper circle for the tubular body which is to be fianged. The innerframe is drawn back to spread the vise-rolls, and the Hanging-rolls 61and 62 are swung outward until the tubular body D to be treated can beinserted over the roll 3 and its shaft and su pporting-bracket. Theinner frame is next forced inward until the tubular body is grippedclosely between the rolls 3 and 4. rlhe Hanging-rolls 61 and 62 areswung inward, and the machine is set in motion, causing the tubular bodyDto rotate on its own axis. While thus rotating' the i slide-bars 68 and69 are drawn to force the Hanging-rolls 61 and 62 radially outward fromthe axis of rotation of the tubular body D or from the aXis of rotationof the roll 8, and the combined rotation of the tubular body and theHanging rolls, which is brought about by frictional contact with thebending-flange of the tubular body, forces the flange outward until itlies at the desired angle with the body of the tubular body. The innerframe is then drawn backward to spread the rolls 3 and 4, theHanging-rolls turned outward, the flanged tubular body removed, andanother one inserted.
